Week 22

Week 21

Jakob, Zlatko and Emir inspected the prototype display for bad soldering.

Emir and Zlatko corrected some bad soldering on prototype display, and experimented with the CA and CK display.

Jakob and Nasko made some oscilloscope measurement with the ADC connected to the fan. Emir and Zlatko experiment multiple display addresses.

We decide to investigate if it possible to make the upgrade of our project with a two digit display. We will decide what we will do on the meeting on Monday.

week 20












Our diagram for Windsensor.














Our diagram for both 7.s. Displays.

Nasko have investigated about the windsensor, and Jacob helps him with ADC, and Nasko will continue the work for one more week.


We have finished our first prototype digits of our display but it didn’t work.

We suspect it could either be soldering errors or program errors.

week 19

Nasko  made some mesurements, and a setup for making a test inviroment for the windsensoir. The full dokument is in the dropbox.
here is a picture of the test inviroment:


















Nasko made messurement and this is the resoult:









































We found the datasheets and placed them in the Dropbox.

Jakob investigateded a way to connect the I/O chip to the NXT.
This is the way we think it will be connected:
Connection diagram
for next time we will try to connect the wires and see if it will start.



week 18

We decideed to research the 7 segment display whith a I/O chip.

We decideed to research the windsensor.

We decided not to make the coffee machine application, the reason is in the meeting folder on dropbox.

Week 17

We investigated which chip me could maybe use and put the datasheets in the DropBox folder.
